That check wasn't enough to handle appending a two byte character
following it.
This prevented my T400 (Intel Core 2 Duo P8400) from attaching;
it would panic from a stack overflow detection.
This update brings initial support for Haswell GPUs.

Differential Revision: https://reviews.freebsd.org/D5554
This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.
